Via: Ars Technica’s Add Internet addiction to psychiatric disorders, says doctor
My favorite bit (link inside linked page!):
“In that study, fMRI scans that can examine activity in specific brain regions while subjects carry out tasks were used to examine activation profiles in the brains of subjects playing a video game, and many of the same pathways involved in drug dependence and addiction were activated, at least in the male subjects.”
I know a lot of women who anecdotally knew this without the fMRI data. My own addiction? A sweet, sweet game called Myth, which allowed one to play relatively well over dialup. Plus, surly dwarves with bombs.
